Description

  The present invention relates to an electronic apparatus such as a digital camera including an exterior cover member having an opening for arranging a liquid crystal display device or the like.

  In recent digital cameras and the like, in addition to downsizing, there is a demand for an increase in the screen size of a display device such as a liquid crystal disposed on the back surface. Therefore, the exterior cover arranged on the back side of a digital camera or the like has a frame shape having a relatively large opening corresponding to the screen size of the display device, so that the width of the frame portion becomes narrow and the rigidity is inferior. Become.

  In addition, in order to reduce the thickness of digital cameras and the like, there is an increasing number of products that omit the transparent window member that is attached to the exterior cover to protect the display device, and the rigidity of the exterior cover tends to further decrease. .

  For this reason, a technique has been proposed in which a screw inserted from the upper surface side of the outer cover is directly fastened to an internal part, thereby increasing the rigidity of the outer cover and preventing the deformation of the outer cover due to an impact at the time of dropping or the like. However, since the operation member is disposed on the upper surface portion of the exterior cover, it is not preferable in terms of appearance to expose the head of the screw.

  On the other hand, a technique has been proposed in which the inner surface of the abutting portion is fastened by an adhering portion in a state where the rear exterior cover and the front exterior cover are directly abutted in the thickness direction of the camera (Patent Document). 1).

  In this proposal, since screws are not used, the deformation of the exterior cover on the back side and the exterior cover on the front side when an impact force is applied by dropping or the like is suppressed without impairing the appearance of the top surface of the exterior cover. I can do it.
